'Letters' in the Bible
Hezekiah sent messages throughout Israel and Judah; he even wrote letters to Ephraim and Manasseh, summoning them to come to the Lord's temple in Jerusalem and observe a Passover celebration for the Lord God of Israel.
Messengers delivered the letters from the king and his officials throughout Israel and Judah. This royal edict read: "O Israelites, return to the Lord God of Abraham, Isaac, and Israel, so he may return to you who have been spared from the kings of Assyria.
He wrote letters mocking the Lord God of Israel and insulting him with these words: "The gods of the surrounding nations could not rescue their people from my power. Neither can Hezekiah's god rescue his people from my power."
